  • Patent number: 9832492
    Abstract: A system, method and apparatus of distributing a video stream is provided. At a publishing point relay, a plurality of video files encoded from a portion of the video stream from a Hypertext Transfer Protocol (HTTP) Adaptive Bit Rate (ABR) video encoding device are received. Each of the encoded video files having a different bit-rate, the encoded video files received using a protocol for transferring files. Edge publishing point servers are determined that are registered with the publishing point relay to distribute the audio/video stream. Each of the encoded video files received by the publishing point relay are relayed to each of the determined edge publishing points as each video file is received from the HTTP ABR video encoding device.
    Type: Grant

  • Patent number: 9106934
    Abstract: A system, method and apparatus of distributing a video stream is provided. At a publishing point relay, a plurality of video files encoded from a portion of the video stream from a Hypertext Transfer Protocol (HTTP) Live Streaming (HLS) Adaptive Bit Rate (ABR) encoding device are received. Each of the encoded video files having a different bit-rate, the encoded video files received using a protocol for transferring files. Edge publishing point servers are determined that are registered with the publishing point relay to distribute the audio/video stream. Each of the encoded video files received by the publishing point relay are relayed to each of the determined edge publishing points as each video file is received from the HTTP ABR encoding device.

  • Publication number: 20080091345
    Abstract: Disclosed is an indoor location system that uses an electrical power line, power line signal injection devices, and portable position receivers (tags) to generate location data relating to positions of the tags in a structure such as a residence or business. The indoor location system fingerprinting of multiple signals transmitted along the power line to achieve sub-room-level localization of the positioning receivers. Details regarding power line positioning are described along with how it compares favorably to other fingerprinting techniques.

  • Publication number: 20070214292
    Abstract: Systems and methods for archiving a stream of sensor data, are disclosed. One method comprises: receiving a stream of sensor data from at least one corresponding sensor device; storing the sensor data to a corresponding capture buffer; receiving, from a trigger device, a request to archive a portion of the capture buffer; and responsive to the archive request, copying the requested portion of the capture buffer to an archive buffer. The sensor device has a coverage area, and the trigger device is located proximate to the sensor coverage area. A user explicitly originates the archive request through the trigger device.

  • Publication number: 20070103552
    Abstract: Systems and methods for controlling or effectively disabling recordation by a camera in an environment are disclosed. One system embodiment includes, among others, a detector and a neutralizer disposed in the environment and coupled to each other. One method embodiment, among others, includes emitting light or a signal into the environment, detecting a camera in the environment, and neutralizing the ability of the camera to capture an image with light emitted from a light source.

  • Patent number: 7003737
    Abstract: A system and method for displaying, browsing and accessing content in real space and time. In one embodiment, a user may browse and access multiple types of electronic content in a three dimensional representation of real space and time, where each document has a time and space attribute. A user may also place electronic documents at different locations in real space and time. A user performs inquiries by moving a space indicator along a time line. A visual indicator representing a relevancy score may provide information regarding document proximity to a selected location in space and time. The relevance score may also offset uncertainties inherent in location tracking systems. A document window is provided to display documents located at a selected point in space and time. Visual indicators associated with the documents may represent the time and space location of each document. Documents in the document window may be sorted as desired by a user.
